Abstract
The invention relates to a punching and drawing method of a cap-shaped casing body. A cap shape is punched on a flat plate, the included angle between the tangent, which is at the connection position of the cap shape with the flat plate, and the flat plate is 140 to 160 degree; a notch is punched at the lower part of the cap shape; the cap shape is punched and drawn into an arc-shaped top and a cylindrical side part, the notch is positioned both on the arc-shaped top and the cylindrical side part; another notch coincident with the notch on the top is punched on the arc-shaped top. The method ensures the accuracy of the notch, and makes the misalignment of the notch on the arc-shaped top and with that on the column side part be less than 0.03mm.
Description
Technical field
The present invention relates to the punching-dragging process method of the crown housing of cap, specifically, is the punching-dragging process method of top and sidepiece at the crown housing of cap the crown housing of cap that the integrated otch of high accuracy is arranged.
Background technology
The crown housing of cap generally after a dull and stereotyped upper punch pulls into shape again through shearing and plate isolation and obtain.If top and sidepiece at the crown housing of cap have the otch that is connected as a single entity, the punching-dragging process method of this cap hat row housing generally comprises following steps: go out outstanding crown on flat board; On crown, go out otch; Crown dashing pulled into arc surfaced top and cylindrical lateral portion two parts, and described sidepiece is perpendicular to flat board, and otch is simultaneously on arc surfaced top and cylindrical lateral portion.
May be because crown dashing when drawing to arc surfaced top and cylindrical lateral portion two parts to otch arranged, that organizes is mobile restive, the shape of the otch on the crown housing of the cap that causes this method to obtain, size and designing requirement deviation are bigger, and deviation is irregular, the otch randomness that obtains is bigger, restive.Therefore common method can't obtain otch high-precision, that be connected as a single entity at top and sidepiece.And, the otch of arc surfaced top and cylindrical lateral portion in drawing process easily positioning cause otch in the otch at arc surfaced top and cylindrical lateral portion not overlap outward appearance is had some setbacks, deviation is at least at 0.1～0.15mm.
Summary of the invention
The present invention solves is the low problem of cut precision that is connected as a single entity at top and sidepiece that the punching-dragging process method of the crown housing of existing cap obtains.
The punching-dragging process method of the crown housing of cap that should integrated otch be arranged at the top and the sidepiece of the crown housing of cap may further comprise the steps:
A. go out outstanding crownly on flat board, the tangent line of this crown and dull and stereotyped joint is 140 °-160 ° with dull and stereotyped angle;
B. go out otch in crown bottom;
C. crown dashing pulled into arc surfaced top and cylindrical lateral portion two parts, described sidepiece is perpendicular to flat board, and otch is simultaneously on arc surfaced top and cylindrical lateral portion.
D. go out another otch that overlaps with above-mentioned notch portion on the top again at the arc surfaced top.
Improvements with respect to existing processes of the present invention are:
1, the tangent line of the crown and dull and stereotyped joint among the step a is 140 °-160 ° with the angle of flat board; Perhaps this angle guaranteed with crown dash pull into arc surfaced top and cylindrical lateral portion two parts after, the otch distortion on the cylindrical lateral portion is less.
2, the otch of designing requirement being divided into two steps comes die-cut, first die-cut a kerf crown, then crown dash pulled into arc surfaced top and cylindrical lateral portion two parts, can obtain the otch that size, shape meet the demands substantially in cylindrical lateral portion (but the otch at arc surfaced top not symbol require); Go out another otch that overlaps with above-mentioned notch portion on the top again at the arc surfaced top.This another otch and last notch portion are overlapping, and the outline of two otch has been formed the otch that meets design requirement.
This processing method has guaranteed the precision of otch to make that the otch on arc surfaced top and the cylindrical lateral portion becomes one that otch requires misalignment less than 0.03mm, and the outward appearance vision is smooth and easy.
As further improvement, following step a is arranged before step a
2: on the circumference that leaves the flat board of preparing to go out crown peripheral certain distance, go out at a plurality of deep-slotted chip breakers.These deep-slotted chip breakers be used on flat board, go out crown.
Further improve, the otch among the step b and the junction of adjacent deep-slotted chip breaker be in the radial direction same again, and be preferably in step a
2Before following step a is arranged
1: with step b in otch going out groove with the periphery of the junction of same deep-slotted chip breaker in the radial direction.The junction of otch and adjacent deep-slotted chip breaker same in the radial direction, described groove all is in order to guarantee the stretching of otch in subsequent handling.
Arbitrary processing method for above-mentioned has following step e after the steps d: go out a plurality of cut-out grooves on flat board and circumference that cylindrical lateral portion links to each other.The cut-out groove has been arranged, the crown housing of the cap of gained can have been separated smoothly with dull and stereotyped.

The specific embodiment
Embodiment:
The punching-dragging process method of the crown housing of a kind of cap has x shape otch at the top of the crown housing of this cap, and four ends of x shape otch extend to the sidepiece of the crown housing of cap.
May further comprise the steps:
a
1. referring to Fig. 1, on the circumference 1 on dull and stereotyped 10, go out four sections grooves 2.
a
2. referring to Fig. 2, go out four sections deep-slotted chip breakers 4 on the circumference 3 of circumference 1 inboard, the periphery of the junction 5 of adjacent deep-slotted chip breaker promptly is a groove 2.
A. referring to Fig. 3,4, on dull and stereotyped 10, to go out outstanding crownly 6, the tangent line of this crown and dull and stereotyped joint is 150 ° with the angle of flat board; Crown periphery leaves the deep-slotted chip breaker certain distance.
B. referring to Fig. 5, go out four otch 7 in crown bottom; The junction 5 of otch 7 and adjacent deep-slotted chip breaker is in the radial direction same.
C. referring to Fig. 6,7, crown dashing pulled into arc surfaced top 8 and cylindrical lateral portion 9 two parts, described sidepiece 9 is perpendicular to flat board, and otch 7 is simultaneously on arc surfaced top 8 and cylindrical lateral portion 9.
D. referring to Fig. 8, go out into the otch 11 of X-shape again on arc surfaced top 8, four ends of otch 11 and four otch 7 on the arc surfaced top partially overlap.
E. referring to Fig. 9, dull and stereotyped 10 with circumference that cylindrical lateral portion links to each other on go out four sections and cut off grooves 12, cut-out groove 12 communicates with deep-slotted chip breaker 4.
In the above-mentioned steps, circumference 1, circumference 2 are coaxial.
The crown housing of cap (referring to Figure 10) by this processes is shaped overlaps at the otch at arc surfaced top and the otch of cylindrical lateral portion, and the outward appearance vision is smooth and easy, and otch requires misalignment less than 0.03mm.Overall appearance is qualified, reaches designing requirement.
